QFontDialog: How to set it size?

mireiner

Hi there,

I like to increase the size of a QFontDialog but my code doesn't work:

#include <QApplication>
#include <QFileDialog>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    a.setAttribute(Qt::AA_EnableHighDpiScaling);
    a.setDesktopSettingsAware(true);

    QFileDialog FileDialog(nullptr);
    FileDialog.resize(1600,800);
//    FileDialog.setGeometry(100, 100, 1600, 900); -> not working also

    QString filePath = QString("/home");
    QString fileFilter = QString("Textfile (*.txt)");
    QString selectedFilter;
    QString fullPath = FileDialog.getOpenFileName(nullptr, "File Save As", filePath, fileFilter, &selectedFilter);

    return a.exec();
}

My system:
Arch Linux
KDE Plasma 5.20.2 desktop
Qt 5.15.1

How to increase the size of QFontDialog?

@mireiner said in QFontDialog: How to set it size?:

FileDialog.getOpenFileName(nullptr, "File Save As", filePath, fileFilter, &selectedFilter)

That's a static methd, calling that equals calling QFileDialog::getOpenFileName(...).
So your setting on FileDialog will not have any effect on it.
Just use non-static methods.

Sorry, I'm a beginner. I already thought that I used the non static method because I didn't use QFileDialog::getOpenFileName(..) in my code.

Can you please provide a short code snippet for the non static method?

Somehow you asked about QFontDialog, but you are using QFileDialog in the code...
For QFileDialog, https://doc.qt.io/qt-5/qfiledialog.html#details, start reading from "You can create your own QFileDialog without using the static functions."
For QFontDialog, the doc doesn't write that in detail, but it is just similar to QFileDialog.

Oh, sorry that was a typo.

Thank you for the link to the documentation, I will read this part carefully.
